Approach:

• Very-low power consumption, MIMO-friendly architectures for ultrahigh speed wireless links
  Based on modern state of the art receiver architectures like direct conversion, new radio concepts will be developed. The main focus is on current saving techniques and on reconfigurable analog front ends, to support MIMO- architectures and multi-standard concepts respectively. These adaptive front ends are the core building blocks for future MIMO analog Subsystems. The principle architecture is shown in the graph below.
  
  
• Technology evaluation for ultrahigh frequency Front End concepts
  Deep-sub-micron CMOS will be analyzed with regard to its RF-capability in the range of 5 to 60GHz.
  
  
• RF-Subsystems for new adaptive MIMO -friendly analog Front End architectures
  For the new WIGWAM air interface physical layer, RF- and base band building blocks as well as a complete 5GHz RF-subsystem will be designed. To cover the higher frequency bands of 17/24 (60)GHz, the 5GHz-receiver is also extended to a multiband architecture, reusing the 5GHz subsystem as an IF-chain.
